Question

Show transcribed image textCreate a rectangular pulse of width 7. Evaluate the DTFT and plot it. Repeat the previous experiment with a rectangular pulse of width 5 and another one of width 9. Compare the resulting DTFTs. Deduce analytically (in the paper) the convolution between the pulse of width 5 and that of width 9. Validate the previous result in Matlab with conv. Now you are going to show that the multiplication in the frequency is equivalent to the convolution in time. Multiply the DTFT for both signals and obtain the inverse DTFT (by using ifft).
